Weighing in at 17 billion solar masses, NGC 1277 contains the largest black hole discovered to date. What makes this black hole exceptional it not just its size, but also that it does not seem to follow the relationship between most supermassive black holes and their host galaxies known as the M-sigma relation. The author’s discuss their findings and possible implications.
